Csound is a software synthesis package in the tradition of so-called
music-N languages, among which the best-known is Music V. It consists
of an orchestra- and score-driven executable, written in C for
portability. Since Csound is a computational language, it is highly
flexible and efficient; complexity is gained only at the expense of
computation time. Basically Csound reads some files and creates the
result as a file on disk or, on faster machines, through a DAC in real
time.
